Use the Flesh to knock player off ledges, but only attack head on when there is only one person or they have one life. Use the Potatoes on groups (because they act like splash potions), or when you are trying to escape but try to avoid the effect yourself. Go up and use your Rotten Flesh after you land 2-3 potatoes on them, you should be able to kill them using 1-2 hits. Avoid Chickens because they can kill you extremely easily.
